LG Optimus 3D has gained a lot of attentions due to its glasses free 3D technology. In this post, we will share all what we know about this smartphone, such as tips and tricks, up ROM, backup, how to capture and share 3D videos and photos, and play NVIDA Tegra 2 games on this smartphone.

1. About LG Optimus 3D

This 3D smartphone was first introduced in MWC 2011 forum in Feb 2011. It is the second 3D devices from LG (after LG Optimus Pad 3D tablet).

Tri-Dual technology: One of remarkable features of Optimus 3D is tri-dual technology. Tri-dual is dual-core (dual-core processor), dual-channel (RAM) and dual memory (storages: built-in and microSD). The following figure shows the difference between RAM of LG Optimus 3D and that of HTC EVO 3D:

The dual-channel helps to reduce the time for accessing RAM and, therefore, this smartphone runs smoother.

- Change EV (controlling the brightness of videos based on the light of environment).

- Change resolution.

- Other settings: stabilization, white balance, …

It’s rather easy to capture 3D videos with this smartphone. Only 2 things you need to consider: 1) you should turn on the stabilization feature and 2) the white balance is not good in low light environments, you should change the white balance setting manually for better results.

3D movies on LG Optimus 3D: To play movies on LG Optimus 3D, the 3D file format must be SBS/Half-SBS/Over-Under.

To install Theme for LG Optimus 3D, you need to have ClockworkMod Recovery and feature “install zip from sdcard”, which will be discuss in details in the next section. Until now, not many themes are designed for this smartphone. You can choose your theme at http://forum.xda-developers.com/forumdisplay.php?f=1077

Others

- The built-in storage (LGE folder) already has LG Optimus 3D drivers for PC and PC Suite. You don’t need to download them from Internet.

- To capture screen without rooting, press Power button and then quickly press Home button. The captured images will be saved in CapturedImage folder in the built-in storage.

- When receiving an incoming call, rotate your phone to turn off the sound.

- You can use the Facebook icon to update which music you’re listening to Facebook

- Sound files recorded by the recorder will be saved in the SoundRecoder folder in the built-in storage.

- To download everything from the web browser, you can use ASTRO File Manager and chose “Enable Browser Download” in Preferences.

4. Up ROM

ROM is a OS version of our smartphone. ROM may be supported from LG or other communities on internet.

Important notes before Up ROM!

- If you do not follow the instructions correctly, your smartphone may be bricked.

- After downloading ROM, copy it into your sd card. You should place it in _ExternalSD folder.

- Run ClockwordMod ROM Manager and chose “Reboot into Recovery”

- After accessing to Recovery, you use the Up and Down volume buttons to move and use Power button to choose. Choose “install zip from SD card”

- Choose “choose zip in sdcard” and browse to the ROM file to install. After installing, go back to the first menu and choose “reboot system now”. If your phone does not reboot, unplug the battery and boot manually.

Note: if you up a completely new ROM, you need to format your phone first. Otherwise, errors may occur. To format you phone, run “wipe data/factory reset” and “wipe cache partition” in ClockworkMod Recovery. Remember to backup your data first.

5. Backup with ClockworkMod Recovery

- Reboot to ClockworkMod Recovery mode by using ROM Manager app or hold Power button and Down volume button at the same time when booting your phone.

- Using volume buttons to move to “Backup and restore” and choose it.

- Choose “Backup”

To restore, use “Restore” in “backup and restore” instead. Note: the restore process takes time.

6. Play NVIDIA Tegra 2 games on LG Optimus 3D

NVIDIA Tegra games are developed for Tegra platform so we cannot play them directly on LG Optimus 3D. To play these games, you need a tool named ChainFire3D (a OpenGL driver). Your phone need to be rooted first.

For 3d photos sharing I recomend to use free app Phereo 3d. This app uses Phereo.com service. Service allows you to upload stero photos, group them in albums and, more importantly, allows you to view it in all possible modes, including anaglyph, and 3d vision right on the site. Users can leave comments and rate photos by clicking "like" button. Phereo 3D allows to browse through thousands of 3D images and share your own stereo photos on Phereo.com. Application shows stereo on HTC EVO 3D and LG Optimus 3D: fully supports their stereoscopic displays and built-in stereo cameras.

I drained my optimus 3d battery for the 1st time yesterday and now it wont start. It shows the LG logo and Orange and then goes into loop mode with those two. Plus it makes a weird vibration before each such "cycle". Pure and simple it wont start. I tried removing the battery, removing the SIM, changing the SIM with no luck. I tried charging the battery fully, with no luck :((

"I drained my optimus 3d battery for the 1st time yesterday and now it wont start. It shows the LG logo and Orange and then goes into loop mode with those two.

I tried charging the battery fully, with no luck :((Have you encountered such a problem. What would u recommend?"

Additionally I tried removing the battery for 5, 10 min , and 1 hour, pressing the power button and the volume (+/-) simultaneously and in sequence, changed even the battery with a friend's (thinking that if the battery was drained it might have been damaged in the process), nothing seems to work. It is stuck into this loop.

Tried to connect it to laptop, won't see the device (used to see it in the past).

I haven't encountered such problem. I think your device may be damaged. You should bring it to the mobile phone shop or the warranty service for fixing. Usually, if you drop your electronic device into water, you should turn it off and remove battery immediately. Then, using the hair-dryer to dry your device before plugging battery again and turning it on.
